Prototype 9, Infiniti’s 1940s EV racer

On August 12, Infiniti launched its Prototype 9, a one-off concept developed to reproduce a 1940s race car using today’s technology.

The “9” in “Prototype 9” was selected for its Japanese pronunciation “kyuu” which is same as the alphabet “Q” employed in Infiniti’s model lineup. This concept was designed at Infiniti Design Studio in Atsugi City, Kanagawa Prefecture and manually assembled at Nissan’s Oppama Research Center in Yokosuka City.

The Prototype 9 is a open-wheel (single-seat) car that measures at 4,330 x 1,820 x 910mm (length x width x height). The wheelbase is 2,700mm long and this low and lightweight race car features a minimum ground clearance of 65mm and cargo weight of 890kg.

According to Infiniti, the Prototype 9 will come loaded with a next-gen EV powertrain that is currently not available on any vehicle on the market. The newly developed motor generates 148hp of maximum output and 32.6kgm of maximum torque. It reaches speeds of up to 170km/h and accelerates from 0 to 100km/h in 5.5 seconds. Equipped with a 30kWh lithium-ion battery, the Prototype 9 can be driven at full throttle on circuits for around 20 minutes.
